JOHN G. BAADER, OF PITTSBURG, ASSIGNOR OF ONE-HALF TO JOHN C. GRADY AND JOSEPH M. GAZZAM, OF PHILADELPHIA, PA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 240,356, dated April 19, 1881.

Application filed March 10, 1881.

To all whom it may concern Be it known that I, JOHN G. BAADER, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it, reference beinghad to the accompanying drawings, which form part of this specification.

My invention has relation to the improvements for which Letters Patent of the United States dated May 4, 1875, and May 20, 1879, respectively, were granted to me, and my present improvements refer particularly to thefollowing points: first, to means whereby the bolt which enters the coupling-link may be located outside of or in front of the car-sill, the extension of it which carries the impellingspring being-back or inside of the front line of said sill and beneath the platform; second, to the construction of said bolt in two detachable pieces, whereby the forward end thereof, or that portion which enters the draw-head and which is liable to be bent by draft exerted through the coupling-link, may be separated from the part which carries the im pellin g-sprin g without disturbing the position of said lastnamed part; third, to the combination, with said bolt, of a guiding-rod for steadying the motion of the former and insuring its accurate entrance to the further opening in the draw-head fourth, to the provision of means whereby said bolt maybe locked when engaged with the link and also when drawn out of the draw-head; fifth, to certain details of construction and combination hereinafterfully set forth.

In the accompanying drawings, Figure 1 is an inverted view, partly in section. Fig. 2 is a vertical section of the draw-head. Figs. 3 and 4 are detail views of the pin and coupling-link.

A designates a draw-head of substantially the same construction as shown in my aforesaid patents.

'5 shows the device illustrated in my patent of May 20, 1879, and therein designated as a trap, having ears 10 p, which cover the boltopenings r r in the draw-head.

(Model) a, in Figure 1, represents that portion of toe bolt which is encircled by the impelling-sprin g, and is supported in an L-shaped plate secured to the under side of the platform of the car. This portion of the bolt, it will be observed, is in the rear of the front or outer edge of the platform, said front having a face-plate, H.

m is a cross-head or yoke, secured to the bolt, as shown, so as to movewith it. This cross-head projects througha slot in the face-plate and receives atits outer end the bolt 0, which enters the opening in the draw-head to engage with the coupling-link. The bolt is fitted securely in the cross-head, yet in such manner that when bent by draft through the coupling-link it may be taken out and replaced without disturbing the yoke, or that portion of the bolt which is surrounded by theimpelling-springn. The other end of the yoke carries a rod, b, which passes through aprojectin g sleeve or pipe on the outside of the draw-head, and thence into said draw-head, back of thetrap This rod serves as a guide for the bolt 0, steadying the latter and insuring its accurate entrance to the further opening in the draw-head when said bolt shoots forward to engage with the link. The object of this construction-i. 0., having the portion of the bolt which engages with thelink out of line with that part which is encircled by the spring-is to adapt the coupling to cars having very thick sills. It is desirable to keep the spring-encircled portion under the platform, and therefore in the rear of the front edge of thelatter; but were the forward end of the bolt in line therewith in cars having thick sills it would be so far back in the draw-head as to be out of reach of, or chance of engagement with, a coupling-link of the ordinary length. The construction described avoids this, the spring-encircled portion remaining under the platform, while the part which engages with the link, being forward of the front edge of said platform, is therefore'sufficiently near the mouth of the draw-head to properly engage with acoupling-link of ordinary length.

Where .cars with narrower or ordinary sills have the improved coupling herein described applied to them the entire bolt may be in a straight line and the cross-head dispensed with. In such case the bolt is made in two separate pieces, held together by a union or coupling, t, as shown in Fig. 3. In this case, as in the construction already described, the part of the bolt which enters the draw-head may, when bent or broken, be detached from the other or spring-encircled part without disturbing the position of the latter.

13 represents the lever for actuating the bolt, said lever being fulcrumed on the front of the platform. To prevent unauthorized movement of said lever the bolt isprovided at its inner end with a hook, g, which may be engaged with a loop, g, secured to the -plate h. Until such engagement is released the bolt cannot be drawn out of the draw-head nor the coupled linkwithdrawn from the latter.

To avoid coupling in shifting cars, which is sometimes desirable, the bolt may be prevented from entering the draw-head bypulling it back until its swiveled hook is brought into engagement with a depending rod or keeper, 70, secured to the platform.

L represents the coupling-link, which is a bar with lateral openings 1 l. NVithin these openings are placed india-rubber plugs or blocks 1 l, which operate as buffers and relieve the strain imposed upon the bolt which passes through the link, or mitigate the shock of bumping.

To couple with ordinary links and pins the draw-head may have the customary vertical openings 00.

What I claim as my invention is- 1. The coupling-bolt made in two sections or parts, one of which is encircled by an impelling-spring and adapted to restand move beneath the platform and back of the edge there of, while the other part is constructed and de signed to be located in front of the platform-sill, substantially as and for the purpose specified.

2. The coupling-bolt made in' two separable pieces to permit removal of the forward end, when bent or broken, without disturbance of the other or spring-encircled end, substantially as shown and described.

3. The combination of the spring-encircled part a, the yoke m, and bolt 0, substantially as shown and described.

4. In combination with spring-bolt C n, having yoke or cross-head m, the guide-rod 12, substantially as shown and described.

5. The combination of bolt composed of two parts, 0 n, connecting cross-head m, and guiderod 1) with L-plate hand face-plate H, slotted for said cross-head, substantially as shown and described.

6. In combination with bolt 0 it, having hook g, the supporting-plate h, having loop-g for engagement therewith and to prevent unauthorized withdrawal of said bolt, substantially as shown and described.

7. In combination with bolt 0 1%, having hook g, the hanger or keeper 70, whereby said bolt may be prevented from shooting forward in shifting cars, &c., substantially as shown and described.v

8. The link L, having cushion or buffer plugs or blocks l l in the bolt-openings, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 10th day of February, 1880.

JOHN GEORGE BAADER.
